Effectiveness of suppressed shotguns

Recently I questioned the effectiveness of suppressed shotguns. This is what a reader sent me …

I read the article about the suppressed shotgun and your question about the effectiveness of the sound reduction. Then I remembered a brochure I picked up at the IWA guntrade-fair in Neurenberg-Germany some years ago about the Laporte Swing Trap shotgun with the integrated suppressor, which reduces 15 % noise with standard ammo and up to 75 % with subsonics. I can not validate this claim because I have only held the gun at the IWA and never fired it, but maybe it is of interest to the readers of the blog.

The company does not appear to manufacture them anymore.

UPDATE: Mark sent me the patent for the Laporte shotgun suppressor. It is an interesting design. Also of note is that the shotgun has a very short barrel (relative to the normal length of these trap guns). The PDF can be viewed after the jump.

    Could such a suppressor also change the nature of the sound enough to make the difference between someone calling 911 immediately, and someone just hearing a strange noise that he doesn't really know what from and therefore doesn't do anything about?

    If you get awakened by ANY loud noise, I think that latter response is most likely, IF THE NOISE IS NOT REPEATED.

    (Yes, I am thinking in context of Chigurh's use of such in No Country for Old Men).

    In the video I posted on my site a while back -- spun off of never knowing shotguns had suppressors till I came here -- seems to show very low noise. Are they using bird-shot (or something similarly small with not much powder backing it up)? In other words, using a suppressor for anything outside of quail hunting, not scaring the birds as much maybe, is just useless?
